Trewellard (from Cornish: Trewylard, meaning "Gwylard's settlement"; grid reference SW376337) is a small village on the north coast road between St Just and St Ives in Cornwall, England, United Kingdom. It lies along the B3306 road, which connects St Ives to the A30 road. It is situated 7 miles (11.27 km) from Land's End and 7 miles (11.27 km) from Penzance. It is in the civil parish of St Just and the electoral division of St Just in Penwith.

Trewellard lies within the Cornwall Area of Outstanding Natural Beauty (AONB). Almost a third of Cornwall has AONB designation, with the same status and protection as a National Park.

The village is in an area of outstanding natural beauty and a Site of Special Scientific Interest (SSSI) due to the ancient tin workings and the penultimate working tin mine in Cornwall, Geevor, that closed finally in 1990. Geevor is now a museum and forms part of the World Heritage Site of Cornwall and West Devon Mining Landscape. Down the lane from Trewellard is Levant Tin Mine, which was the site of a terrible accident in 1919 where 31 men were killed. It has been long since closed and is owned by the National Trust, which operates it as a museum.
